operation with the binding surface 15, lies .in the path of the foot 14 and contacts with the foot to limit the stroke of the pump.v One feature of my invention is thepositions occupied by thebinding surfaces 15 and 23 with relation to each other, these surfaces being so disposed that though great upwardlpressure be exerted upon the rack it cannot be made to bender slip away fromthe stop, but will be held against lateral movement with respect thereto. A spring 24 secured to the stop at one end contacts with its free end against the barrel of the pump A. and serves lto retain .the stop against casual dislodgment 'from either of its pivot- `ally adjusted positions.' For convenience in manipulation a handle 25 protrudes prefer-` ably from the segmental detent 20, and for further convenience a. plate 26 is positioned upon thevcuter periphery of the stop andv bears any suitable legend such as lon. i

In the operation of the pump the. turning of the handled crank 18 causes upward movement of the rack 10 and the foot 14. That stop which designates theamount of fluid which it is desired todischarge from the pump is thrown into the position illustrated in Fig. .3 and when the foot 14 has risen to that stop the two bind-ing surfaces l5 and 23 contact and prevent the discharge One galfrom the pump of more than the desired.

quantity. lf it be found that the quantity discharged by the pump when the stop 14 and thejdetent have met is incorrect, the seal 27 is removed, the sleeve. 17 rotated upon the threaded rod 16 until the proper point is reached, and the seal again set in place.

ln the accompanying drawings and in the foregoing description is set forth the preferred embodiment of my invention, but it is obvious that one skilled in the art may make modifications thereof without departing from the spirit of the invention,

1. The combination of a threaded rod, a sleeve threaded upon the i rod and having peripheral flanges at its ends, ay stop pro-. jecting laterally of the rod and fitted for rotation 'about the sleeve and between the flanges thereof, and means fonseeuring the sleeve and stop in fixed relation.

2. The combination of a threaded rod, a movable sleeve threaded upon the rod, and having peripheral flanges at its ends, and a stop projecting laterally of the rod, disposed about the sleeve andfitted rotatable between the flanges thereof.

3. The combination of a threaded rod, a movable sleeve threaded upon the rod, and having peripheral flanges at its ends, and a stop projecting laterally of the rod,disposed about the sleeve and lfitted between the.A

flanges thereof, said stop being formed of two pieces removably secured together.

the remainder of the parallel and adjacent to the rod, a segmental stop of greater width than the distance between the rod and the wall, disposed about part of the sleeve and' fitted between the flanges thereof, and a yoke secured ltothe ends of the segmental stop disposed about sleeve and fitted between the flanges thereof, said yoke being at its center of lesser Width than the distancev from the rod to the wall. 1 5. The combination of a threaded frod, a movable sleeve threaded upon the rod and having peripheral flanges at its ends, a wall parallel and adjacent to the rod,a segmental stop of greater width than the distance between the rod and the wall, disposed about part of the -sleeve land fitted between the flanges thereof, a yoke secured to the ends of the segmental stop disposed about'the remainder of the' sleeve and fitted between the flangesthereof, said yoke being at its center of lesser width than the distance from 9o therodx to the Wall., and means for securing j the stop and sleeve in fixed relation.

6. The combination of a threaded rod, a movable sleeve threaded upon the rod and Y having peripheral flanges at its ends, a wall parallel and adjacent to the rod, a segmental stop of greater width than the distance between the rod and the wall, disposed about part ofthe sleeve and fitted between the flanges there'ola yoke secured tothe ends 100 flanges thereof, said yoke being!1 at its center of, lesser widthv than the distance from the rod to thewall, and a seal .passing through 105 the stop, yoke, and sleeveand securing the stop and yoke in fixed relation to the sleeve.

7. The combination of athreaded rod, an A adjustable pivoted stop thereon, a wall adjacent and parallel to the rod, uand a spring member in 'contact with the stop and wall and for movablv maintaining' the stop in position at either end of its path of pivotal movement.

8. The combination of a rod. a stop pivot- 1.15

ed upon the rod an l`adjusta=ble longitudin nally thereof, a wall parallel and adjacent to the rod and with which the stop contacts at each end of its path of pivotal movement,`and meanscoperating with the wall and stop to maintain the stop movable .in position at either end of its path of pivotal movement.

9. The combination ofv a threaded rod, a sleeve threaded upon the rod and having peripheral flanges spaced apart, a-segmental stop secured about the sleeve and fitted be- 'tween the flanges thereof, said sleeve being movable upon the rod, a wall adjacent the l rod, mea-ns for securing the sleeve and Stop I 3:1 fixed relation said segmental Stop being of Sucut width i0 contact with the cmu at mvh 0F its ends, and u spring member* '.fml'vd hv the stm) :md contuctug; wh the, vsnll 'for romovnbly maintaining The @top wtm when c'xthe' of its @ms is 'm nimmst with. the wall.
